PPC is used for setting system performance profiles including clocks for CPU, GPU, and memory.

[9.0.0+] The PPC system module is now stubbed and all its services were moved into PTM.

apm

This is "nn::apm::IManager".

This was moved to AM with [8.0.0+] and is now a shim for apm:am.

Cmd Name
0 #OpenSession
1 GetPerformanceMode
6 [7.0.0+] #IsCpuOverclockEnabled

OpenSession

Returns an #ISession.

IsCpuOverclockEnabled

No input, returns an output u8 bool.

apm:p

This is "nn::apm::IManagerPrivileged".

This service no longer exists in [8.0.0+].

Cmd Name
0 OpenSession

OpenSession

Returns an #ISession.

apm:am

This is "nn::apm::IManager".

This was added with [8.0.0+] and is the same as the old apm service.

apm:sys

This is "nn::apm::ISystemManager".

Cmd Name
0 RequestPerformanceMode
1 GetPerformanceEvent
2 GetThrottlingState
3 GetLastThrottlingState
4 ClearLastThrottlingState
5 [5.0.0+] LoadAndApplySettings
6 [7.0.0+] #SetCpuBoostMode
7 [7.0.0+] #GetCurrentPerformanceConfiguration

GetPerformanceEvent

Returns an #ISession.

SetCpuBoostMode

Takes an u32 #CpuBoostMode.

GetCurrentPerformanceConfiguration

Returns the currently active #PerformanceConfiguration (default value is 0x00020003).

ISession

This is "nn::apm::ISession".

Cmd Name
0 SetPerformanceConfiguration
1 GetPerformanceConfiguration
2 [8.0.0+] #SetCpuOverclockEnabled

SetPerformanceConfiguration

Takes an u32 #PerformanceMode and an u32 #PerformanceConfiguration.

GetPerformanceConfiguration

Takes an u32 #PerformanceMode and returns an output u32 #PerformanceConfiguration.

SetCpuOverclockEnabled

Takes an input u8 bool, no output.

fgm, fgm:0, fgm:9

This is "nn::fgm::sf::ISession".

Cmd Name
0 Initialize

IRequest

This is "nn::fgm::sf::IRequest".

Cmd Name
0 Initialize
1 Set
2 Get
3 Cancel

fgm:dbg

This is "nn::fgm::sf::IDebugger".

Cmd Name
0 Initialize
1 Read
2 Cancel

CpuBoostMode

Value Description
0 Disabled.
1 Boost CPU. Additionally, throttle GPU to minimum.

Use performance configurations 0x92220009 and 0x9222000A, or 0x9222000B and 0x9222000C.

2 Conserve power. Only throttle GPU to minimum.

Use performance configurations 0x9222000B and 0x9222000C.

PerformanceMode

Value Description
-1 Invalid
0 Normal
1 Boost
